Description
Technical field
The present invention relates to the Compressor Technology field, particularly relate to one-sided spring Linearkompressor.
Background technique
Compressor is a kind of from energy output machinery (such as motor) received energy, improves the machinery of gas pressure or conveying gas in order to pressurized gas.Usually, compressor can be divided into reciprocal compressor, rotary compressor and scroll compressor.Wherein the reciprocal compressor working principle is that working medium is inhaled into the compression volume between piston and the cylinder, and piston is done straight reciprocating motion with compressed gaseous working medium in this cylinder, and after compression working medium rising pressure is discharged from compression volume.
Traditional reciprocal compressor adopts electric rotating machine to promote, and needs such as mechanical parts such as bent axles rotatablely moving of drive motor to be converted into the straight reciprocating motion of piston, owing to huge energy loss has occured conversion of motion.In the Linearkompressor, piston is directly connected on the linear electric motor that carry out straight reciprocating motion, has reduced the energy loss of bringing because of conversion of motion, can further improve compression efficiency and simplifies its structure.Because Linearkompressor can be less than the more energy-conservation while noise of other compressors, has been applied to household electric appliance, for example refrigerator.
In existing Linearkompressor, the general employing in the linear motor rotor both sides arranged resonant springs, and Fig. 1 is the structural representation of prior art neutral line compressor.As shown in Figure 1, the conventional linear compressor comprises: the parts such as Aspirating valves 15 and outlet valve 16 consist of compressor suction and discharge unit 10; The cylinder 30 of compressor; Piston 20 at cylinder 30 interior moving linearlies; The linear electric motor 40 that formed by mover 45 and stator 41; Spring 51, spring 52, spring 53 and spring 54 etc. consist of the resonant springs unit 50 of Linearkompressor; Oil pump 60.The head a initial position of Linearkompressor piston 20 is near its reciprocating centre of oscillation, namely is near the point midway of compressor piston stroke H.Cylinder 30 forms a compression volume with the piston 20 of section's moving linearly within it, motor stator 41 and mover 45 consist of linear electric motor 40 together, electric mover 45 links to each other with piston 20, drive piston 20 at the reciprocal straight line motion of cylinder 30 interior works, spring 51, spring 52, spring 53 and spring 54 etc. consist of the resonant springs unit 50 of Linearkompressor, are assemblied in the both sides that the Linearkompressor moving element is electric mover 45 after the precompressed.
The said structure operational instruction of conventional linear compressor is as follows:
When linear electric motor 40 are operated, produce linear reciprocating motion under the effect in the magnetic field that the magnet on the mover 45 of linear electric motor 40 produces around the coil on the stator 41, the mover 45 of linear electric motor 40 drives piston 20 continuously to-and-fro motion between upper dead center T and right side lower dead centre B in cylinder 30 inside.
When piston 20 lower dead centre B when motion to the right, Aspirating valves 15 is opened under the pressure difference effect, working medium is sucked in the compression volume of cylinder 30 and piston 20 compositions, spring 53 and spring 54 etc. are further compressed simultaneously, and the decrements such as spring 51 and spring 52 reduce, after piston 20 moves to lower dead centre B place, the moving direction of piston 20 changes, and beginning is to the motion of upper dead center T position, and this moment, Aspirating valves 15 cut out, finish the breathing process of compressor, working medium is inhaled in the compression chamber.
On the other hand, when piston 20 moves to lower dead centre B position, its speed vanishing, moving direction changes, begin to the left upper dead center T position motion, this moment, Aspirating valves 15 cut out, and working medium begins compressed, and spring 51 and spring 52 etc. are further compressed simultaneously, the decrements such as spring 53 and spring 54 reduce, after the power pressure in the compression volume of piston 20 and cylinder 30 compositions increased to the exhaust pressure value of design, this moment, outlet valve 16 was opened, and compressed working medium is discharged from compression chamber.After piston 20 moved to upper dead center T position, outlet valve 16 was closed, and exhaust process finishes, and the moving direction of piston 20 changes, and began to the right lower dead centre B motion.Because piston 20 subsequently moves right, working medium will be inhaled in the compression chamber of piston 20 and cylinder 30 compositions, and after this aforementioned operation will repeat.
Yet in the above-mentioned traditional compressor, arrange in the linear motor rotor both sides resonant springs to be operated in the optimum state for making Linearkompressor, usually make the natural frequency of the ac frequency that drives linear electric motor work and compressor close.Quality and spring rate by the compressor moving element are mated the working power frequency, thereby the spring resonant element rigidity of configuration is large, and the spring consumption is more, and the Linearkompressor heavy moving parts is larger, from product material-saving angle, also need to improve further.
